# Note that the query itself should return the following four columns:
# 'type' (your special page's name), 'namespace', 'title', and 'value'
- # *in that order*. 'value' is used for sorting. These may be stored in
- # the querycache table for expensive queries, and that cached data will
- # be returned sometimes, so the presence of extra fields can't be
- # relied upon.

# Don't include an ORDER or LIMIT clause, this will be added.
